You can lower your triglycerides through a combination of dietary changes, exercise, and weight management, often seeing measurable results within a few months. A triglyceride level below 150 mg/dL is considered normal by the American Heart Association, and if yours is above that, the changes below can make a real difference. Triglycerides are one of the most diet-responsive blood markers, meaning lifestyle adjustments tend to move the needle faster than they do for other cholesterol numbers.
Cut Back on Sugar, Especially Fructose
Reducing added sugar is one of the single most effective things you can do. When you eat more sugar than your body needs for immediate energy, your liver converts the excess into triglycerides and packages them into particles that circulate in your blood. Fructose is particularly problematic because it bypasses a key regulatory checkpoint in the liver that normally slows down fat production. Glucose has a built-in bottleneck. Fructose skips right past it, flooding your liver with raw material for fat synthesis.
This matters practically because fructose isn’t just in fruit. It’s a major component of table sugar, high-fructose corn syrup, sweetened drinks, flavored yogurts, cereals, and condiments. The World Health Organization recommends keeping free sugar below 10% of your daily calories, and ideally below 5%. On a 2,000-calorie diet, that 5% target is about 25 grams, roughly the amount in a single can of soda. Swapping sweetened beverages for water or unsweetened drinks is often the highest-impact single change people make.
Eat More Soluble Fiber
Soluble fiber slows digestion, reduces sugar absorption, and helps your body clear fats from the bloodstream more efficiently. The National Lipid Association recommends 5 to 10 grams of soluble fiber per day, which can lower total and LDL cholesterol by 5 to 11 points. While those numbers refer to cholesterol specifically, the same fiber-rich foods (oats, beans, lentils, barley, flaxseed, apples, citrus fruits) support healthier triglyceride metabolism by reducing the flood of sugar and fat that reaches your liver after meals.
Five grams of soluble fiber is about a bowl of oatmeal plus an apple. Ten grams is achievable if you add a serving of beans or lentils to lunch or dinner. These aren’t dramatic dietary overhauls. They’re substitutions: oatmeal instead of a pastry, lentil soup instead of a sandwich, an orange instead of juice.
Move Your Body Consistently
Regular aerobic exercise lowers triglycerides by helping your body break down and clear fat-carrying particles from your blood more efficiently. Research on patients with heart disease found that moderate-intensity exercise, performed five times per week for eight weeks, produced significant triglyceride reductions. Each session was 45 minutes total, including a warm-up and cool-down, with the core exercise done at 60% to 80% of maximum heart rate. That’s a pace where you can talk but not sing: brisk walking, cycling, swimming, or jogging.
You don’t need to hit that exact schedule to benefit. Any increase in regular movement helps. But consistency matters more than intensity. Three moderate walks per week will do more for your triglycerides over time than one intense weekend workout followed by six sedentary days.
Lose Even a Small Amount of Weight
Triglycerides are unusually responsive to weight loss. Research shows that even patients who lost less than 5% of their starting body weight saw a significant drop in triglycerides. Those who lost 5 to 10% saw even greater reductions. For someone weighing 200 pounds, that’s a loss of just 10 to 20 pounds.
This is encouraging because it means you don’t need to reach an “ideal” weight to get meaningful results. The triglyceride benefit kicks in early, often before you notice major changes in how your clothes fit. If you’re making the dietary and exercise changes described here, some weight loss will likely follow naturally.
Rethink Your Relationship with Alcohol
Alcohol raises triglycerides by slowing your body’s ability to break down fat after meals. Normally, an enzyme called lipoprotein lipase clears fat-carrying particles from your bloodstream. Alcohol inhibits that enzyme, causing those particles to pile up. The result is a spike in triglycerides that can last for hours after drinking.
Moderate drinking (one to two drinks per day for women, one to three for men) has minimal measurable effect on triglyceride levels. But beyond that threshold, the impact climbs quickly. If your triglycerides are already elevated, cutting alcohol entirely for a few months is a reasonable experiment. Many people are surprised by how much this single change moves their numbers.
Consider Omega-3 Fatty Acids
Omega-3 fatty acids from fish oil are one of the best-studied supplements for lowering triglycerides, and they work in a dose-dependent way: each additional gram per day reduces triglycerides by roughly 6 mg/dL, with stronger effects in people who start with higher levels. A large review of 86 clinical trials, covering over 162,000 participants, found that omega-3 supplementation reduced triglyceride levels by about 15% on average.
For people with significantly elevated triglycerides, the American Heart Association recognizes that prescription-strength omega-3s at 4 grams per day can produce substantial reductions. That dosage is well above what you’d get from a standard fish oil capsule, which typically contains 300 to 500 mg of combined EPA and DHA. Eating fatty fish like salmon, mackerel, or sardines two to three times per week provides a meaningful dietary dose without supplements, and carries additional cardiovascular benefits.
Choose Better Fats
Replacing some of the saturated fat in your diet with unsaturated fats from sources like nuts, olive oil, and avocados supports overall cardiovascular health, even though the triglyceride-lowering effect of this swap alone is modest compared to the changes above. Think of it as one piece of a larger strategy rather than a standalone fix. Practical swaps include cooking with olive oil instead of butter, snacking on walnuts instead of chips, and choosing fish over red meat a few times per week.
How Quickly You Can Expect Results
Triglycerides respond to lifestyle changes faster than most other blood markers. If you make several of the changes described here simultaneously, you can expect to see measurable improvement on your next blood test, typically within two to four months. In clinical follow-ups, patients making sustained lifestyle changes have seen dramatic reductions tracked at four-month intervals over a year.
The key word is “sustained.” A two-week burst of clean eating before a blood draw will produce some short-term improvement, but triglycerides reflect your ongoing dietary and activity patterns. The changes that stick are the ones you can maintain without white-knuckling it: smaller portions of sugar rather than zero sugar forever, walks you actually enjoy, fish dinners you look forward to. Small, permanent shifts beat dramatic temporary ones every time.
